Arguments are fields that are given to a method when it is called, while parameters are the name for the received variables. For example:public static void main(String[] args){int arg1 = 0;boolean arg2 = false;String arg3 = "Some string";function_a(arg1, arg2, arg3);// These variables are called arguments because they are being passed// to the function.}public static void function_a(int par1, boolean par2, String par3){// These variables are called parameters because they are being received// when the function is called.}I hope this helps.
